(1, 2), (4 , y) ,(x , 6) and (3, 5) are the vertices of a parallelogram taken in order, then the value of x and y are
Answers
Step-by-step explanation:
In parallellogram diagonals bisect each other.(x,y)=(6,3)
Answer:
(x,y) = (6,3)
Step-by-step explanation:
Given points are :
A(1,2),B(4,y),C(x,6),D(3,5)
ABCD is a parallelogram.Let O be the centre such that O is the midpoint of AC & DB.
Mid point formula =( x₁+x₂ , y₁+y₂ )
2 2
Mid point of BD = ( 3+4 , 5+y )
2 2
= ( 7 , 5+y )
2 2
Mid point of AC = ( 1+x , 2+6 )
2 2
= ( 1+x , 8 )
2 2
= ( 1+x , 4 )
2
Equating abscissa
1+x = 7
2 2
1+x = 7
x = 7-1
x = 6
Equating ordinate
4 = 5+y
2
8 = 5+y
y = 8 -5
y = 3
Thus (x,y) = (6,3)
